[Max the Man]

And aren't we missing some recurring enemies? Adamantoise... goblins...

I'll give a description cause I feel like it:

Adamantoise: First apearance: FFII Appearances: FF's 1, 2, 3, 4... you get the picture. Adamantoise are known for their HUGE HP ammount and their high defence, but if you can find their weakness, you'll beat them in no time.

Goblins: First apearance: FFI Appearances: All FFs except for 8, 10 and 12
Their known for being one of the first monsters you fight and for having that annoying skill Goblin Punch which randomly damages one of your party.

Ochu: First appearance: FFI Appearances: FF 1, 7, 8, 9, 10, X-2
Ochu are known for their poisonous attacks and their high HP and magic tolerances. Actually, an Ochu is one of a number of optional bosses in FFX.

add any more if you can think of them, I haven't played an FF for a while x_x;;
